Behavioral symptomatology was compared in 26 children and adolescents with Autistic Disorder ("autism") and 25 children and adolescents with Pervasive Developmental Disorder, Not Otherwise Specified ("PDD-NOS"). Relative to individuals with PDD-NOS, those with autism had more symptoms of depression, social withdrawal, atypical behavior, and immature social skills--and fewer family problems. These differences remained even when group differences in intellectual ability were statistically controlled. No group differences emerged in somatization, anxiety, or hyperactivity. Findings suggest that although both groups demonstrate considerable evidence of behavioral and emotional problems, those with autism are at particularly high risk for comorbid behavioral and emotional disabilities.

Blood-based tests for the differential diagnosis of Alzheimer's disease (AD) are under intensive investigation and have shown promising results with regard to Abeta40 and Abeta42 peptide species in incipient AD. Moreover, plasma Abeta40 was suggested as an independent cerebrovascular risk factor candidate. These considerations prompted us to analyse a total of 72 plasma samples in vascular dementias (VAD, n = 15), AD with cerebrovascular disease (AD with CVD, n = 7), AD (n = 15), Parkinson's disease and Parkinson's disease dementia (PD/PDD, n = 20) and 15 patients with depression that served as controls (DC) for distinct plasma amyloid-beta (Abeta) peptide patterns. For the analysis of plasma we used immunoprecipitation followed by the quantitative Abeta-SDS-PAGE/immunoblot. For comparison, CSF tau and Abeta1-42 analyses were performed. The major outcome was an increase in Abeta1-40 in plasma of VAD paralleled by a decrease in the ratio of Abeta1-38/Abeta1-40. The ratio Abeta1-38/Abeta1-40 in plasma enabled contrasts of beyond 85% and 80% for discriminating VAD from DC and all other patients, respectively. In CSF, we confirmed the typical CSF biomarker constellation of increased tau and diminished Abeta1-42 levels for AD. The diagnostic accuracy of plasma Abeta1-38/Abeta1-40 for VAD resembled the accuracy of CSF biomarkers for AD. From the presented results, we consider the ratio of plasma Abeta1-38/Abeta1-40 peptides to be a blood-based biomarker candidate for VAD.

Cognitive and affective dysfunctions are frequent but often neglected symptoms in Parkinson's disease (PD). We developed the screening tool Parkinson neuropsychometric dementia assessment (PANDA) with five cognitive tasks and a short depression questionnaire. Healthy subjects and patients without cognitive impairment (PD), mild cognitive disorder (PD-MCD), or dementia (PDD) were examined. The cognition part had a specificity of 91% and a sensitivity of 90% for PDD and 77% for PDD plus PD-MCD patients. The mood questionnaire also had high sensitivity and specificity. We conclude that the PANDA is an economical, easy-to-use and sensitive tool to detect neuropsychological dysfunctions in PD patients in clinical practice.

Psychiatric symptoms were retrospectively assessed in a clinic population of 241 children and adults with tuberous sclerosis complex (TSC). Sixty-six (27%) patients had a history of mood disorder symptoms, 66 (27%) had a history of anxiety disorder symptoms, 73 (30%) had a history of attention-deficit hyperactivity disorder (ADHD) symptoms, and 68 (28%) had a history of aggressive/disruptive behavior disorder symptoms. Significant relationships were found between these symptoms and patient age, gender, genetic mutation, seizure history, surgical history, cognitive impairment, features of autism or pervasive developmental disorder, and neurological manifestations of TSC. In 43 patients seen by at least one of two affiliated psychiatrists, the most common formal diagnoses were anxiety disorders (28%), mood disorders (26%), adjustment disorders (21%), ADHD (21%), and mental disorders not otherwise specified due to general medical condition (42%). Citalopram demonstrated efficacy in treating anxiety and depression, and risperidone, in treating problematic behaviors.

Impairment in different cognitive domains such as executive functions, language, memory, and visuospatial skills occurs frequently in Parkinson disease (PD) even in the early stages of the disease. Although frank dementia (Parkinson disease dementia, PDD) is less frequent, risk for developing dementia is two to six times greater than the prevalence rate in general population and it increases in relation to disease duration. Clinically, dementia in PD is characterized by uninsidious onset and slowly progressive cognitive decline, with a predominant dysexecutive syndrome accompanied frequently by a variety of behavioral symptoms such as hallucinations, depression, anxiety, and excessive daytime sleepiness. Although the exact pathophysiology and neurobiological basis of PDD is not known, dementia in PD probably develops as a result of progressive involvement of subcortical and cortical structures by Lewy-type pathology and associated Alzheimer-like histological changes. Dysfunction of different monoamine transmitter has also been implicated in the cognitive deterioration of PD but reduced cholinergic activity in the cortex is thought to account for the strongest mechanism in the development of dementia. Recent evidence suggests that cholinesterase inhibitors are effective in the treatment of dementia and accompanying behavioral symptoms in PD.

Attention-deficit/hyperactivity disorder (ADHD) is typically characterized by inattention, excessive motor activity, impulsivity, and distractibility. Individuals with ADHD have significant impairment in family and peer relations, academic functioning, and show high co-morbidity with a wide range of psychiatric disorders including oppositional defiant disorder (ODD), conduct disorder (CD), anxiety disorder, depression, substance abuse, and pervasive developmental disorder (PDD). Family studies suggest that ADHD + CD represents a specific subtype of the ADHD disorder with familial risk factors only partly overlapping with those of ADHD alone. We performed a hypothesis-free analysis of the GAIN-ADHD sample to identify markers and genes important in the development of conduct problems in a European cohort of individuals with ADHD. Using the Family-Based Association Test (FBAT) package we examined three measures of conduct problems in 1,043,963 autosomal markers. This study is part of a series of exploratory analyses to identify candidate genes that may be important in ADHD and ADHD-related traits, such as conduct problems. We did not find genome-wide statistical significance (P < 5 x 10(-7)) for any of the tested markers and the three conduct problem traits. Fifty-four markers reached strong GWA signals (P < 10(-5)). We discuss these findings in the context of putative candidate genes and the implications of these findings in the understanding of the etiology of ADHD + CD. We aimed to achieve insight into the genetic etiology of a trait using a hypothesis-free study design and were able to identify a number of biologically interesting markers and genes for follow-up studies.

We report the case of a female in her 40s diagnosed with depression. She was raised by an eccentric father, suspected of having pervasive developmental disorder, and a dominant mother. After graduating from high school, she worked as a clerk in a company for twenty years or so; however, a change in her work environment made her fall into a depressive state. Her worsening depression caused her impulsive resignation and disappearance for about four months. She spent the duration of her disappearance traveling the country, with no dissociative episodes. After returning, she received treatment for depression as an inpatient for about four months. During the first month of hospitalization, she mainly complained of a depressive mood and anxiety over the prognosis of her disorder, while she made scarcely any progress in introspection. In the second month, she gradually advanced with introspective work, but, as her introspection progressed, her depressive mood became aggravated. The therapist avoided intervention to modify her cognition, and told her the following: "it is better not to persist in managing your depressive mood itself because curing depression does not mean resolving the superficial depressive mood, but to achieve a condition not directly influenced by mood." Then, at the beginning of the third month, she became aware of "the presence of God" and, at the same time, her depressive mood greatly improved. She extended her sympathy to her mother with her unfortunate life history, and expected her mother to change as she herself had experienced, but, disappointed by her mother, she experienced anxiety attacks and came to realize her own internal rage against significant persons in her life including her mother. After "the Great being" experience, she, who had formerly attended Christian church for a short time, started to read the Bible, but she still hesitated about committing herself to "religious following." One day during the last month of hospitalization, as she prayed to God for healing when she read a part in the Bible about a woman suffering from a hemorrhage for twelve years who touched the hem of Jesus' garment and was healed immediately (Matthew 9:20-22 and Luke 8:43-48), the patient suddenly experienced "the salvation of God" and realized what trust really meant. Through the experience, her clinical problems became totally cured, and the therapy concluded with her discharge from hospital. Several months later, she sent the therapist a letter including the following message: "I am grateful to the Lord for salvation from anxiety and irritation, but to the therapist for helping me realize it." This clinical course can be understood based on the patient's clinical problems (e.g., despair, anxiety, and depression), arising from the breakdown of her efforts to maintain stability by founding her psychological base on her feelings of omnipotence, avoiding facing her internal negative psychological factors (e.g., rage), and these were automatically resolved when her psychological base was switched to the transcendent level through "the Great being" experience and "the salvation of God." Such a sudden, marked improvement resembles what Miller and C'de Baca reported as "quantum change," of which the characteristics are vividness, surprise, benevolence, and permanence. The therapist paid attention to maintain a constant psychological distance from the patient, not persisting in modifying her cognition, with the transcendent level being the basis for the entire therapy. This stance of the therapist itself was considered to prompt her transcendence and bring about her eventual cure. This clinical course seemed to be highly suggestive of a psychotherapeutic mechanism, indicating the close relationship between the transcendent level and basic trust.

Studies on the distinction between Autistic Disorder (AD) and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) have been inconclusive. This study examined the validity of PDD-NOS by comparing it to AD and other developmental disorders (DD) on parent-reported behavior problems. Fifty-four children with PDD-NOS were individually matched on age and non-verbal IQ to 54 children with AD and 54 children with DD. Groups were compared on select subscales of the Child Behavior Checklist. High rates of psychopathology were observed in both ASD groups. The only difference between PDD-NOS and AD groups was higher scores in the PDD-NOS group on two items measuring Anxiety/Depression. Cognitive functioning may be a more salient variable than subtype when studying psychopathology in individuals with ASDs.

Despite the frequency and importance of dementia associated with Parkinson's disease (PDD) and dementia with Lewy bodies (DLB), there is relatively little evidence on which to base treatment. Evidence from meta-analysis suggests that rivastigmine can improve cognition and functioning in PDD and also reduce risk of falling. There is also evidence supporting its use in DLB. Recent evidence suggests that memantine may also be effective, particularly for PDD, although evidence is more conflicting. Memantine may also improve parkinsonism and dyskinesias. Few clinical trials of cognition in PD without dementia exist, but there is preliminary evidence for atomoxetine, memantine, and piribedil. There is a lack of systematic evidence for the treatment of visual hallucinations and depression in PDD and DLB. In addition, there is a need for studies of whether potentially disease-modifying agents can prevent or delay the progression to dementia in PD.

We used a national online registry to examine variation in cumulative prevalence of community diagnosis of psychiatric comorbidity in 4343 children with autism spectrum disorders (ASD). Adjusted multivariate logistic regression models compared influence of individual, family, and geographic factors on cumulative prevalence of parent-reported anxiety disorder, depression, bipolar disorder, and attention deficit/hyperactivity disorder or attention deficit disorder. Adjusted odds of community-assigned lifetime psychiatric comorbidity were significantly higher with each additional year of life, with increasing autism severity, and with Asperger syndrome and pervasive developmental disorder-not otherwise specified compared with autistic disorder. Overall, in this largest study of parent-reported community diagnoses of psychiatric comorbidity, gender, autistic regression, autism severity, and type of ASD all emerged as significant factors correlating with cumulative prevalence. These findings could suggest both underlying trends in actual comorbidity as well as variation in community interpretation and application of comorbid diagnoses in ASD.
